Graphing Motion: Key Concepts and Techniques

What does a straight line on a position-time graph indicate about the object's motion?

• The object is accelerating.

• The object is at rest.

• The object is moving backward.

• The object is moving forward.

In a position-time graph, what does the x-axis represent?

• Velocity in meters per second

• Position in meters

• Time in seconds

• Acceleration in meters per second squared

What is the formula for velocity?

• v = t/d

• v = d/t

• v = d * t

• v = t - d

How is the slope of a position-time graph related to velocity?

• Slope equals velocity

• Slope equals distance

• Slope equals time

• Slope equals acceleration

If the y-axis value is 4 meters and the x-axis value is 8 seconds, what is the velocity?

• 0.5 meters per second

• 4 meters per second

• 8 meters per second

• 2 meters per second

What is the first step in calculating the slope of a position-time graph?

• Divide the time by the distance

• Subtract the initial position from the final position

• Add the coordinates

• Multiply the coordinates

When using coordinates to determine slope, which coordinate is subtracted first?

• Final time

• Initial position

• Final position

• Initial time

What does the triangle symbol (Δ) represent in the slope formula?

• Difference

• Product

• Sum

• Change

What does a downward slope on a position-time graph indicate?

• The object is moving forward

• The object is at rest

• The object is accelerating

• The object is moving backward

What is the relationship between slope and velocity on a position-time graph?

• Slope equals velocity

• Slope equals time

• Slope equals distance

• Slope equals acceleration
